Epic fail while trying out the new KKmulticoper 2.0 Flightcontrol board. It seems like sloppy calibration and speed reading the manual rewarded me with six broken Hexacopter arms. It was also my first attempt at controlling the multicopter with my smartphone and the Kickstarter funded iPhly device. Definitely a steeper learning curve to fly by touch screen and gyroscope than traditional joysticks. Amazingly all six birch propellers survived, perhaps saved by the hopelessly brittle acrylic frame. Back to the drawing board.
